IMPROVEMENT IN COUPLlNG-FAUCETS.

Specification forming part of Letters Patent No. 119,243, datedSeptember 26, 1871.

To all 'whom z'tmag/ concern.-

Beit known that I, OLIVER SALGEE, of the city of Brooklyn, in the countyof Kings and State of New York, have invented an Improve ment inCoupling-Faucets; and the following is declared to be a correctdescription thereof.

Faucets for beer-barrels have been made with a tapering end, to bedriven into the bung-hole and screwed into the same tightly; and to suchfaucets the tube leading to the fountain or drawing-faucet has beenconnected. These faucets, however, are costly and liable to get out ofrepair. I make' use of a valve opening inward and introduced in theplug, in combination with a coupling-screw and thimble, in such amannerthat the screwing in of the coupling opens the valve of the faucet toallow the contents of the barrel to pass off by said tube. The valve isself-closing upon the coupling' being detached. The seat of the valve ismade movable, and the leather surface of the seat is clamped around itsedges by screwing the seat to place.

In the drawing, Figure 1 is a longitudinal section of the said faucet,and Fig. 2 is a cross-section at the line w llhe tapering plug a, with ascrew-thread upon its surface, is of thev usual charactenV b-is thefemale screw for the coupling-thimble c and ring d; and these parts areeither inV line with the plug a or at an angle thereto, as required forthe direction in which the pipe is to pass away from the thimble c. Thevalve t is made with guidewings 2 2 2in the opening through thevalveseat o, and also with a stein, 3, passing through a bridge orguide, 4; and yaround the stem is the expansive spring a, to close thevalve i against the seato when the coupling-thi1nble c and ring d areloosened or removed; but when these are screwed into place the end ofthe thiinble, acting against the wings 2, opens the valve, so that thecommunication through the faucet and coupling is complete. By this meansthe separate key or cock of the faucet is dispensed with. The leatherface r of the valve-seat o is confined at its edges between said seat oand the ring nf, and the valve-seat o' is movable, so as to be screwedinto the female couplingscrew b and clamp the edges of the elasticvalveFseat r. By making the ring n alglf'liiiiiiltliside of the faucet,and of a diameter to freely admit the valve t' to pass through thesaine, I am enabled to introduce the whole of the parts through thescrewcylinder I), thereby lessening the cost and rendering any secondopening unnecessary. The washer o makes a tight joint between thethiinble c and the valve-seat o.

The coupling-faucets heretofore made are liable to injury in driving inor knocking out, because the barrel of the cock is injured bycompression and hence becomes leaky, and the male thread of the couplingis battered and injured in driving in or knocking out. My valve is notinjured by the concussion, and the coupling being made as a female screwthe thread is protected from injury.

`I claim as my invention- 1. The valve i, with the wings 2 in theopening through the seat o, in combination with the thimble c and ring dof the faucet, as and for the purposes set forth.

2. The valve-seat o, screwed into the female coupling-screwb, andconfining the elastic surface 1" of the seat to the ring fn', incombination with the valve e', thiinble c, and ring d. substantially asset forth.
